x – y = 3
2x = 2y + 6

typically these are a set of simultaneous eqns which will have 2 solns

however the two eqns are
x -y =3
2x -2y = 6 i.e x -y =3

so both the eqns are the same
hence we cannot find a soln, howver we cannot say that there is no soln

coz 6 -3 =3, 10-7 =3 ........ these all can be potential values of x,y

hence we can say that there are infinte possibilites for x & y
so E
